Preferably, described earrings is connected with piston rod thread and is fixed by straight pin.
Preferably, an O RunddichtringO and the 2nd O RunddichtringO are set between described fairlead and cylinder barrel, the 3rd O RunddichtringO is set between described piston and piston rod, providing holes sealing ring and support ring between described piston and cylinder barrel.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, traction lifting suspension bracket oil cylinder, mainly include earrings 1, cylinder barrel 5, piston 8, piston rod 2, fairlead 4, valve block assembly and black box.Arranging rod chamber hydraulic fluid port 11 and rodless cavity hydraulic fluid port 12 on cylinder barrel 5, one end of piston rod 2 is arranged in cylinder barrel 5 and is connected with piston 8, and the other end of piston rod 2 is threadeded with earrings 1 after stretching out fairlead 4 and pass through straight pin 3 fixing.
Valve block assembly includes valve block 6, balanced valve 7 and guard shield 9, valve block 6 is connected to the outside of cylinder barrel 5, balanced valve 7 is arranged in valve block 6, first hydraulic fluid port of valve block 6 connects the first oil pipe 14 by the first end free flow coupling 13, and the other end of the first oil pipe 14 is connected with the rod chamber hydraulic fluid port 11 of cylinder barrel 5 by the first end right angle control joint 15.Second hydraulic fluid port of valve block 6 connects the second oil pipe 17 by the second end free flow coupling 16, and the other end of the second oil pipe 17 is connected with the rodless cavity hydraulic fluid port 12 of cylinder barrel 5 by the second end right angle control joint 18, and all the other hydraulic fluid ports of valve block 6 seal each through guard shield 9.
Black box includes RotoVL sealing ring 19, Wellendichtring 20(axle AQ seals), these special envelope 21, RotoVL sealing rings 19 of the first support ring 22 and two, Wellendichtring 20(axle AQ seal), the first support ring 22 and two these special envelopes 21 are arranged between fairlead 4 and piston rod 2.Oneth O RunddichtringO 23 and the 2nd O RunddichtringO 24 is set between fairlead 4 and cylinder barrel 5, the 3rd O RunddichtringO 10 is set between piston 8 and piston rod 2, providing holes sealing ring 25 and the second support ring 26 between piston 8 and cylinder barrel 5.
